Problems solved by technology
Therefore, same as JP 4-6724 Gazette, JP 2003-290138 Gazette, and JP 2009-172028 Gazette, it is cumbersome and time-consuming to perform adjustment operations.
[0008] In addition, in recent years, lead-free soldering (also referred to as lead-free soldering) that does not contain lead has been widely spread, and in this lead-free soldering, the joint strength may decrease compared with soldering that currently contains lead
In addition, in the case of soldering, the bonding strength is affected due to variations in the amount of soldering, so there is also a problem that defective products with insufficient bonding strength increase and the yield decreases.
In addition, in the case of soldering the wire and the sleeve, the soldering work is difficult because the area to be soldered is small.

Embodiment Construction
[0035] Such as figure 1As shown, the endoscope system is composed of an electronic endoscope (hereinafter, simply referred to as an endoscope) 10 , an information processing device 18 , and a light source device (not shown). This endoscope 10 includes an elongated insertion portion 11 inserted into the body, an operation portion 12 provided on the proximal end side of the insertion portion 11 , and a universal cable 13 . The insertion part 11 is formed in a tubular shape and is composed of a front end part 14 , a curved part 15 and a flexible part 16 in order from the front end. The bending part 15 is comprised by the bending part 15a which bends in an up-down direction, and the bending part 15b which bends in a left-right direction. One end of the universal cable 13 is connected to the operation unit 12 , and the other end of the connection unit 17 is connected to an information processing device 18 , a light source device, and an air and water supply device (not shown).

The invention provides an operational wire connection device which has a pair of semicircular fixing parts, a circular outer screw part and a connecting body, and an endoscope. The fixing parts clamp the end portion of a wire from both sides. The outer screw part has an imbedding portion for accommodating the pair of the fixing parts in the state clamping the wire, and male threads formed on the outer circumferential surface thereof. The connecting body has formed thereon female threads matching with the male threads. During adjusting of looseness of the operational wire, the pair of the fixing parts is drawn out from the outer screw part after the outer screw part is dissembled from the connecting body. After the position of the pair of the fixing parts clamping onto a passive wire has changed, the pair of the fixing parts is embedded in the outer screw part, which is then in thread connection with the connecting body.
Description
technical field [0001] The present invention relates to an operating wire connecting device and an endoscope using the device. Background technique [0002] The endoscope includes a small-diameter insertion portion inserted into the body, and an operation portion provided on the proximal end side of the insertion portion. The insertion part is composed of a front end part, a bending part and a flexible part. The tip portion is formed into a cap shape from a hard resin material, and an objective lens, a solid-state imaging element such as a CCD, an illumination lens, and the like are disposed therein. The bending part bends in the up, down, left, and right directions by rotating the operation adjuster provided in the operation part to advance and retreat the operation wire inserted into the insertion part. Therefore, insertion of the insertion portion into the body becomes smooth, and the distal end portion can be directed toward a desired observation site during observatio...
